Zone Terminal
11
When downloading the ZT without a controller, 24 VAC power must be
accessed from a transformer. Where power is accessed through an
XFR100 transformer, splice the wire coming from the transformer
according to the illustration below. This is only required when you do
not
have an AHU, VAV, or UNT available. Other hardware connections for
downloading are as shown.
Figure 6: Downloading Without an ASC Controller
!
CAUTION: Connect only one transformer at a time into the
AS-CBLCON-0.
Connecting more than one controller at a time may
cause a short circuit.
The ZT must be plugged into a
6-pin
telephone-type
jack. Plugging the ZT into an 8-pin jack destroys the
8-pin receptacle and prevents the ZT from powering
up.
